66084066 ÷ 18 
We're looking to find how many times 18 goes into 66084066.

Let's proceed to step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 18

Going ahead to step 2:
The number 18 fits into 66 3 times, leaving a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 12 after subtracting 54 from 66.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 18

Going ahead to step 3:
If we divide 120 by 18, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 108 from 120 to get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 18

Moving on to step 4:
If we divide 128 by 18, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 367.0
If we take 126 away from 128, we end up with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 18

Going ahead to step 5:
18 goes into 24 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 3671.0
If we take 18 away from 24, we end up with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 18

Let's proceed to step 6:
If we divide 60 by 18, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 36713.0
If we take 54 away from 60, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 18

Step 7:
If we divide 66 by 18, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 367133.0
Subtracting 54 from 66 leaves us with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 18

Going ahead to step 8:
If we divide 126 by 18, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 3671337.0
Subtract 126 from 126 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3671337.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 18, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3671337.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 3671337.0 with a remainder of 0.0.
